Abstract (en)

[origin: EP1182231A1] A high tear strength, low compression set, low cost heat curable silicone elastomer composition comprising: (a) an alkenyl terminated linear diorganopolysiloxane gum; (b) an alkenyl containing diorganopolysiloxane gum; (c) a precipitated silica reinforcing filler with surface area of from about 90 to 300 m<2>/g; (d) a hydroxy terminated polysiloxane fluid; (e) an organohydrogenpolysiloxane; (f) an effective amount of a low compression set additive; and (g) an effective amount of an addition-cure catalyst.
